Aish at Disney's New Groove posted this chart of Disney movies in chronological order according to their historical settings. She posted it with the following note:

"(Excludes most of the package films. Some films, eg The Lion King, are impossible to pin down exactly and some, like Aladdin and Treasure Planet, are anachronistic, so these are estimations. A few have been split into 2 if there is more than one time period in the movie, and sequels have been put together.)"
